This is a valid technique--I once lived in a house that became overrun by mice. I asked the landlord if I could bring in a barncat, and he said yes. Problem solved in the space of weeks.

I did feel sorry for the mice, though.

My Ninja Kitty... But she doesn't kill the mice. She brings them inside for entertainment.

Too bad we haven’t/can’t domesticate barn OWLS.

They kill/eat about 10 times the mice that a cat does.
